A PCB having surge voltage prevention function is provided to simplify a manufacturing process and to reduce a manufacturing cost without an additional protection device by preventing a surge voltage through change of a pattern design of the PCB. A PCB having surge voltage prevention function includes a pattern. The PCB(100) is connected to an AC input terminal(AC in). The pattern has more than two bending parts by a right angle or an angle above the right angle. When the power from the AC input terminal is inputted to the PCB with the pattern, the electrons collides with the bending parts of the pattern. The flow of the electrons is interrupted by the mutual collision between electrons. |
